Operating System Tutorial

Last updated : May 08, 2023

An operating system (OS) is the interface between user and computer hardware. It manages the hardware attached to the computer system. An operating system is a system software. Operating system perform various task regarding computer system like memory management,controlling peripheral devices such as disk drives and printers,handling input and output,file management etc.

This Operating System tutorial contains all the basic to advance operating system topics like Process and I/O Device Management, File and Network Management, Memory Management, Security Management, CPU Scheduling, and more.
